Regardless of the value of "a", our goal in solving a quadratic equation by factoring is to rewrite the sum or difference as a product, and then solve for x using the zero product property. First, make sure your equation is in standard form, meaning exponents are in decreasing order and it's equal to zero. (Many students forget this key first step.) Then look for a greatest common factor, and factor completely. Using the zero product property, set each factor equal to zero and solve for x.
